UnrealMCPPro is a C++ editor plugin for Unreal Engine 5.7 that enables AI assistants (Claude, GPT, etc.) to directly control the Unreal Editor through the Model Context Protocol (MCP). It provides 200+ command handlers across 39 categories, covering nearly every aspect of UE5 development — from spawning actors and creating materials to managing Blueprints, Niagara systems, and Level Sequences.

• AI-Assisted Level Design — Spawn actors, set transforms, assign materials, and build entire scenes through natural language
• Automated Workflows — Create Blueprints, compile, set variables, and manage assets without touching the editor UI
• Full Editor Control — Play/Stop PIE, capture viewports, execute console commands, undo/redo operations
• Production-Ready — WebSocket-based communication with auto-reconnect, JSON-RPC 2.0 protocol, and robust error handling

• Unreal Engine 5.7+
• A compatible MCP server (included with the itch.io download)
• Node.js 18+ (for the MCP server)
